The Procera® System also involves the use of a densely sintered
high-purity zirconia, another ceramic material that can be used
to fabricate copings for crowns, one-piece or multi-unit all-ceramic
bridges, and ceramic implant abutments. These ceramic units are
then combined with low fusing veneering porcelain that creates the
anatomic form of the restoration and the occlusal morphology. The
zirconia material is selected for use because of its outstanding
strength characteristics. Another added feature with this material
is its light color. In the anterior portions of the mouth the lighter
color assists the Ceramists in creating naturalness. The techniques
for using this ceramic material is the same as that used with the
Procera® Aluminum Oxide coping. The individual copings or one-piece
zirconia oxide substructures are manufactured by Nobel Biocare at
their facilities and then returned to the laboratory of origin for
veneering porcelain application and final finishing. The qualities
of Procera® Zirconia Oxide components have been under evaluation
by the Center in various studies. The abstracts and reports
of these studies are presented in this website.
